Meritor Tire Inflation System by P.S.I. Video

Nov. 12, 2015

MTIS by P.S.I. automatically maintains proper and even pressure at all times, and it can be installed on all major trailer axle models in North America. MTIS connects all tires on the trailer to a controlled air supply to fill and maintain tires at the desired pressure setting, even while the vehicle is moving. As air pressure drops below the tire manufacturer’s recommended level, it routes air through a control box and the trailer axles to refill any under-inflated tires.
